Freecom USB DVB-T stick (id 14aa:022b) still doesn't work.

I'm still struggling with this stick. I have now compiled 
the modules for a second P4 based system (my primary requirement is on a Arm 
based system) and see identical results. I 
have also placed this device behing a powered USB hub and I still get "recv 
bulk" errors (-71, -110, -75...) each time I try and use it. A second 
attempt at tuning _always_ results in a system 
freeze.So, one card, two PC's, with or without a hub 
and I get reproduceable (bad) results.

Is 
this likely to be a driver or hardware error?

Cheers

Mark

  (reprise)

  I wrote over the 
  weekend describing the problems I've been having with my Freecom stick (id 
  14aa:022b). I've made some progress but am still struggling with the 
  device.

  Here's the dmesg 
  output
    dvb-usb:

  dvb-usb: 
  WideView WT-220U PenType Receiver (based on ZL353) successfully initialized 
  and connected.
  dvb-usb: recv bulk message failed: 
  -110

  Basically when I 
  attempt to tune it using a channels.conf from another system in my 
  house I get a Tuning failure and (sometimes a kernel OOPS) with recv bulk 
  message errors. However, if I follow the recommendations here (http://www.linuxtv.org/pipermail/linux-dvb/2006-April/009684.html ) 
  and change ythe freq for BBC ONE from 641833330 to 642000000 I get a 
  successful lock. dvbdate from the dvb-apps returns the correct date/time but 
  scan results in a system freeze. Once tuned, all further attemps to retune the 
  device (even to BBC ONE) result in a system freeze. Below is an extract from 
  my (modified) channels.conf

  BBC 
  ONE:642000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_3_4:FEC_3_4:QAM_16:TRANSMISSION_MODE_2K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:600:601:4173

  I'm on 
  a Linksys NSLU2 (slug) running Slugos 3.10. All software is cross 
  compiled on a Gentoo PC.  

  All assistance is 
  greatly appreciated.

  Cheers
